Its a hardware defect on some clip players. I looked into working around it by carefully timing disk access like the sandisk software does but lost interest since my players don't do it and it was hard to test.

saratoga I didn't know about that, wow I should consider myself lucky that my Clips don't do that. Unfortunately I don't have one of those players but if I did, I'd gladly contribute it to you or one of the other devs to hopefully end it.
